佛說觀佛三昧海經 6.9

6.9

「見東方眾生盡是其父；見西方眾生悉是其母；見南方眾生悉是其兄；見北方眾生悉是其弟；見下方眾生悉是妻子；見上方眾生悉是師長；其餘四維悉是沙門、婆羅門等。見是眾生皆受苦惱，或遇重病；或見在於刀山劍樹火車爐炭。一切苦事見已悲泣，欲拔其苦自作我想，乘寶蓮華詣諸人所，調身按摩為洗癩瘡，見地獄火憂悲雨淚欲滅其火。見諸餓鬼，刺身出血化作乳想，供給餓鬼令得飽滿，既飽滿已為其說法，讚佛、讚法、讚比丘僧，作是讚已益更憂悲心無暫捨。如是慈心極令通利，事事廣說如慈三昧，如是慈心名習慈者。

"One sees all sentient beings of the eastern direction as one's fathers; one sees all sentient beings of the western direction as one's mothers; one sees all sentient beings of the southern direction as one's elder brothers; one sees all sentient beings of the northern direction as one's younger brothers; one sees all sentient beings of the downward direction as one's wives and children; one sees all sentient beings of the upward direction as one's teachers and elders; and all in the four intermediate directions as śramaṇas, brāhmaṇas, and the like. Seeing these sentient beings, one sees that they all suffer pain and distress, or encounter severe illnesses, or are on mountains of blades, trees of swords, fire-carts, and burning coals. Seeing all these afflictions, one weeps in compassion and wishes to eradicate their suffering. Generating the thought of oneself, one rides a jeweled lotus and approaches each person: tending their bodies, massaging them, and washing their leprous sores. Seeing the fires of hell, one weeps tears of sorrow and compassion, wishing to extinguish those fires. Seeing the hungry ghosts, one pierces one's own body to draw blood, imagining it transformed into milk, and supplies it to the hungry ghosts so that they are satisfied. Once they are satisfied, one preaches the Dharma to them, praising the Buddha, praising the Dharma, and praising the bhikṣu-Saṅgha. Having sung these praises, one's sorrow and compassion deepen all the more, without pausing for a moment. Bringing such loving-kindness to the utmost proficiency, explaining each matter extensively as in the loving-kindness samādhi—such loving-kindness is called the practice of loving-kindness.
